We’re looking for a Backend Engineer (Security Infrastructure) to ensure that Monzo’s platform and core infrastructure is safe and secure by design.

You’ll help us with the following questions and challenges:

• Securing our critical infrastructure, such as Kubernetes, Cassandra, Kafka, and the AWS services, Data Centres and networks they rely on;
• Providing and managing the foundational infrastructure for other Security and Platform Engineering squads to build upon;
• Managing our secrets, keys and certificates to ensure our systems are airtight;
• Automating access control and permissioning for our cloud infrastructure.

Here are some of the projects the team have worked on in the past:

• Controlling outbound traffic from Kubernetes
• Building our secret management platform
• Building network isolation for 1,500 services

The role

You’ll Be Responsible For

• Ensuring that our cloud infrastructure and physical data centres are secure;
• Building a deep understanding of the security of key technologies such as Vault, Kubernetes, Cassandra, Teleport and AWS and how we can improve them;
• Performing threat modelling to mitigate the most important attack vectors against our infrastructure.

Monzo’s security team has a wide range of responsibilities. As a bank, we are solving diverse, novel problems to ensure that our customers and their data are secure.

One of the guiding principles of security at Monzo is that security at the expense of user experience is a last resort. We aim to move mountains in the background so that we can build world-class features without compromising on security.

As a Backend Engineer in Security you’d be able to work directly with lots of teams across the company, and we run regular knowledge-sharing sessions so you’ll learn heaps about everything; from how banks work to effective communication and the technologies we use.

You should apply if

• You have experience in software engineering (we use Go, but we’re open to all backgrounds) and you’re excited about solving large-scale infrastructure security problems.
• You’re comfortable securing cloud-based environments and networks, and wrangling with code at this level of abstraction.
• You’re passionate about security and understand best practices.
• You’re constantly looking for flaws in systems and can reason about how best to address them.

Logistics

Salary ranges between £75,000 – £100,000 plus stock options and other benefits .

We can help you relocate to London & we can sponsor visas.

This role can be based in our London office, but we’re open to distributed working (with ad hoc meetings in London once COVID is over).

We offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team.

Diversity and inclusion is a priority for us – if we want to solve problems for people around the world, our team has to represent our customers. So we need to attract the best talent and create an environment that supports and includes them. You can read more about diversity and inclusion on our blog .

If you prefer to work part-time, we’ll make this happen whenever we can – whether this is to help you meet other commitments or strike a great work-life balance.

Our interview process is normally an initial phone interview followed by a take-home task and call to discuss it (or alternatively a paired-programming exercise), if successful you will move to a final round of 3 separate interviews conducted via hangouts. We promise not to ask you any brain teasers or trick questions. We might design a system together on a whiteboard, the same way we often work together, but we won’t make you write code on one.
